1807418 - PWAs show an empty space for the toolbar, but only when the toolbar position is ‘Top’

Status: RESOLVED DUPLICATE of bug 1815633

(Fenix :: PWA, defect, P5)

Description

[Chris Peterson [:cpeterson]]

From github: https://github.com/mozilla-mobile/fenix/issues/19972.

Steps to reproduce

1. From the three-dot menu, select Settings > Customize and set:
   • ‘Toolbar’ to ‘Top’
   • ‘Scroll to hide toolbar’ disabled
2. Install any PWA that uses "display": "fullscreen" or "display": "standalone" in its manifest (for these screenshots, I'm using https://davidsekar.github.io/pwa-sample/)
3. Open the PWA

Expected behavior

The PWA should use the entire screen (except for Android UI elements, if "standalone").

Actual behavior

The PWA shows an empty space at the top in the area where the toolbar would appear in Fenix. (Below the status bar, if one is visible, and above the actual app content.)

Here is a table of screenshots (only the top-right is unexpected):
